DETAILED DESCRIPTION OF THE INVENTION
[0073]The following contents simply describe some typical embodiments. As
known by those
people skilled in the art, said embodiments may be amended in different
approaches so long as
they adhere to the principles or fall into the protection scope of the present
invention. Therefore,
the Figures and descriptions are essentially regarded as embodiments rather
than limitation.
[00741 Before a detailed description about typical embodiments, it should be
noted that some
typical embodiments are illustrated as flow charts. Although the flow charts
describe each
13
CA 2971897 2017-06-27
operation in sequence, many operations may be implemented concurrently or
simultaneously. In
addition, the sequence of the operations could be re-arranged. Said
illustration may be ended
when the operations complete, but it may include additional steps not present
in the Figures.
Such an illustration may correspond to a method, a function, a regulation, a
subroutine, a
subprogram, etc.
100751The methods discussed below (some are illustrated by flow chart) can be
implemented by
hardware, software, firmware, middleware, microcode, hardware description
language or any
combination thereof. When software, firmware, middleware or microcode is
employed, the
program coding or code segment used to perform the necessary tasks can be
stored in a machine
or in a computer-readable medium (such as storage medium). One or more
processors are able to
perform necessary tasks.
[0076] Prior to the present application, the management staff generally assign
the maintenance
persons according to flight segments of the aircraft. For instance, if an
aircraft is expected to land
at airport at 9 o'clock and take off at 11 o'clock, one or more maintenance
persons will be
assigned to maintain the aircraft and no other work will be arranged for the
one or more
maintenance persons during this period, no matter whether they can complete
the task in advance
or not.
10077]In the embodiments of the present application, the assignment of
maintenance persons is
refined, making possible a better time division multiplexing for maintenance
persons and higher
level of aircraft maintenance.
[0078] According to one embodiment, the method for maintaining an aircraft
based on the
embodiments in the present application can be implemented by a
computer/computing device,
specifically, by running the software procedure in the computer/computing
device, the
hardware/firmware that form the computer/computing device, and/or the
combination thereof.
The computer/computing device comprises a local storage device and/or a
storage device
remotely accessible by networking. The computer/computing device may become a
part of a
computer system that comprises a memory device able to be communicably
connected to the
computing device through network. The computing device may access the database
in the
storage device to perform the method for aircraft maintenance in the present
application.
14
CA 2971897 2017-06-27
[0079]The database in the storage device include a maintenance task database
and a
maintenance personnel database. For example, the maintenance task database may
store the data
and information linked to each aircraft maintenance task, such as the level,
timing and location
of each aircraft maintenance task. In one embodiment, the task location can be
the parking spot
at an airport for the aircraft, such as the number of a gate, and
relative/absolute location
information. The timing information for the task may comprise task time period
information for
the performance of the aircraft maintenance task (in another embodiment, the
task time period is
the evaluated task time period of the aircraft maintenance task), the
estimated start time and the
estimated end time of the task, the estimated amount of time Ts required by
the task, and the
redundant amount of time AT for aircraft maintenance task. For example, when
the aircraft to be
maintained will land at a parking spot at 11:00 a.m. and take off at 13:00
p.m., the task time
period for aircraft maintenance is from 11:00 a.m. to 13:00 p.m. and the task
location is parking
spot a. The evaluated amount of time Ts required by the task is the evaluated
amount of time
necessary to complete the aircraft maintenance task. For example, a computing
device provides
the estimated amount of time required by the task based on the specific work
of the aircraft
maintenance task and the statistical average amount of time according to the
historical data of
each work or other approaches and then records it in the maintenance task
database. The
redundant amount of time AT for aircraft maintenance task can be a constant,
which may
comprise the travel time spent by the maintenance person from the location of
the prior task or
flight control center to the task location. In one embodiment, AT is set based
on empirical data or
statistical data in order to ensure the maintenance person has sufficient time
to arrive at the
possible far most task location from any potential task location in the
airport within AT amount
of time. In another embodiment, AT may vary according to aircraft maintenance
tasks (e.g.
changes in specific work, location, maintenance level and exceptional cases).
Prior to the
assignment of maintenance persons for an aircraft maintenance task, the
estimated start time and
estimated end time of the task are null. The maintenance task database may
also record the list of
the maintenance persons selected for each maintenance task.
[0080]The maintenance personnel database may record such information as a list
of all
maintenance persons, a list of maintenance persons attending each day, and the
information of
each maintenance person (e.g. basic information, information for task
arrangement, information
CA 2971897 2017-06-27
for available time period, and the average speed Vs, etc). In one embodiment,
the list of all
maintenance persons can be updated periodically, or occasionally or as needed.
The list of the
maintenance persons attending each day can either be recorded by the
management staff into the
database of aircraft maintenance persons, or be exported from an attendance
system and
transferred into the database of aircraft maintenance persons, or stored in
the database of aircraft
maintenance persons through other methods. The basic information of each
maintenance person
may include one or more of the following: name, sex, age, health condition,
maintenance
experience, expertise, and special situation. The information for task
arrangement of each
maintenance person may include, for example, the estimated start time, the
estimated end time
and task location related to each aircraft maintenance task assigned to the
maintenance person in
the predetermined time period (e.g. current day). In one embodiment, the
aircraft maintenance
personnel database also records the available time period (idle time period)
information for each
maintenance person. The idle time period stands for the time period where the
maintenance
person has no assigned aircraft maintenance task, which can be calculated by
the task
arrangement information of the maintenance person.
[0081]Optionally, said maintenance task database and maintenance personnel
database can also
be stored in the local memory device of the computing device. In such an
embodiment, the
computer system performing the method of aircraft maintenance may only consist
of the
computing device without the memory device. The computing device may be in or
not in the
network environment.
I00821In another embodiment, the method for maintaining an aircraft according
to each
embodiment in the present application may be carried out in a server. Figure 1
shows such an
embodiment: computer system 100 comprises one or more computing devices 101,
103 and a
storage device 102, further comprising a server 104 able to be communicably
connected to the
computing devices 101 and 103 and the storage device 102. The server refers to
any remote
computing device that may communicably exchange with the client/client side
device and
comprise a centralized or distributed processor and an optional memory. The
server 104 may
interact with a user (e.g. a management staff) through the computing devices
101 and 103. In
response to the user input/instruction from the computing devices 101 and 103,
the server 104
implements the method for maintaining an aircraft of the present application
by accessing the
16
CA 2971897 2017-06-27
database in the memory device 102 and sends to the computing devices 101 and
103 the result of
the maintenance persons assigned to the aircraft maintenance task. Although
Figure 1 and the
embodiment only show two computing devices, understandably, there could be one
or more than
two computing devices.
[0083] The computing devices 101 and 103 can be a computer, a laptop, a
workstation, an
iPhone, an Android mobile phone, a Pad, and other devices able to access
network and perform
certain data calculations.
[0084]Fig. 2 is a flow diagram showing a method for maintaining an aircraft
according to one
embodiment in the present application. In the following description, the
aircraft maintenance
method is made possible in an embodiment where the computing device access the
maintenance
task database and maintenance personnel database in the memory
device/memorizer. In the
embodiment shown in Figure 2, the aircraft maintenance method comprises the
following steps:
[0085]Step S101, obtaining the location and timing of the current aircraft
maintenance task from
the maintenance task database.
[0086]In the management of aircraft maintenance, the system needs to ensure
that each aircraft
maintenance task has been assigned to the appropriate maintenance person(s) to
perform. After
the assignment of maintenance persons to the current aircraft maintenance task
by the system,
according to the aircraft maintenance method in the embodiment, the computing
device obtains
the location and timing of the current aircraft maintenance task in step SI01.
The task location
for aircraft maintenance can be the current parking spot of the aircraft, such
as the number of the
parking area or relative/absolute positioning information. The time of
aircraft maintenance task
may comprise one or more time information related to the aircraft maintenance
task, e.g. the task
time period information for the performance of the aircraft maintenance task,
the evaluated
amount of time Ts required by the task, and the redundant amount of time AT
for aircraft
maintenance task. Following the assignment of maintenance persons to the
aircraft maintenance
task, the maintenance task database may be immediately updated to record the
estimated start
time and the estimated end time of the aircraft maintenance task. Optionally,
after the aircraft
maintenance task is completed, the maintenance task database may be updated to
record the
actual start time and end time of the aircraft maintenance task.
17
CA 2971897 2017-06-27
[0087]Step S102, obtaining a list of available maintenance persons from the
maintenance
personnel database. The available maintenance persons can be all maintenance
persons attending
on that day.
[0088]Step S103, classifying the available maintenance persons as the first
collection of
candidates. In another embodiment, the available maintenance persons are
screened on the basis
of the maintenance level information of the current aircraft maintenance task
obtained from the
maintenance task database, and then the available maintenance persons meeting
the maintenance
level are classified as the first collection of candidates. The maintenance
level may be
established in view of aviation flight regulations and airline practices,
comprising, for instance,
transit(TR), pre-flight(PF) and after flight(AF). In other embodiments, the
maintenance level
may further comprise regular check, A check, C check, troubleshooting, etc. In
an embodiment,
the maintenance level information is stored in the database accessible by the
computing device
and necessary to perform the method embodiment in the present application,
wherein one
maintenance level corresponds to one or more work consisting of inspection,
maintenance and
repair. For example, transit (TR) may comprise the inspection and supplement
of grease and
hydraulic oil.
[0089]In one embodiment, different maintenance levels need to be performed by
the
maintenance persons with different experiences. For example, the maintenance
for an engine
requires the candidates with experience of engine maintenance. To be sure, the
low-level
maintenance persons can be assigned to handle entry-level maintenance task.
[0090] Alternatively, the screening for maintenance level can be performed
between the steps
S107 and S108.
[0091]Step S104, candidate maintenance persons who have not been determined by
step S105
are selected from the first collection of candidate.
[0092] Step S105, determining if the selected candidates meet the requirements
for the location
and timing of the current aircraft maintenance task. The embodiment for
identification will be
specified below according to Fig. 3.
[0093]As shown in Fig. 3, the process to determine whether the selected
candidates meet the
requirements for such location and timing includes:
18
CA 2971897 2017-06-27
[0094]Step S201, obtaining task time period, task location, Ts and AT from
maintenance task
database for the current aircraft maintenance task. For instance, suppose the
current aircraft
maintenance task's task time period lasts between 8:40 a.m. and 9:40 a.m., Ts
is 24 minutes (0.4
hour), and AT is 12 minutes (0.2 hour).
[0095]Step S202, obtaining the information related to the candidates from the
maintenance
personnel database. Such information may comprise their basic information,
information for task
arrangement, and the average speed Vs. and the like. The information for task
arrangement may
refer to the estimated start time, the estimated end time and the task
location related to each
aircraft maintenance task assigned to the maintenance person in the
predetermined time period
(e.g. current day). Their idling time period can be calculated by the task
arrangement
information. The distance between two task locations can be calculated
depending on the
location of each task.
[0096j1 Step S203, calculating the amount of time T corresponding to the time
period overlapped
by the idling time period of the candidates with the task time period of the
current aircraft
maintenance task. For example, the obtained task arrangement information shows
that the
candidates have two idling time periods: idling time period 1 between 9:00
a.m. and 10:00 a.m.;
and idling time period 2 between 13:30 p.m. and 17:30 p.m. In this case, the
idling time period 1
of the candidates can be used for the current aircraft maintenance task, the
overlapping time
period with the task time period (8:40 a.m. to 9:40 a.m.) is from 9:00 a.m. to
9:40 a.m., and the
amount of time T is 40 minutes (0.67 hour).
[0097] Step S204, determining if T>Ts+2AT.
[0098] If T>Ts+2AT is true in step S204, Step S205 follows, determining the
candidates meet
the requirements for the location and timing of the current aircraft
maintenance task. In light of
the data in the example above, it can be calculated that Ts+2AT is 0.8 hour,
greater than T (0.67
hour), that is, T>Ts+2AT fails.
[0099]If T>Ts+2AT fails in step S204, step S206 follows, determining whether
T>TS+ ( ALI+AL2 ) /VS is true, wherein ALI is the distance between the
location of said current
aircraft maintenance task and the location of the aircraft maintenance task
assigned for the
candidates prior to said current aircraft maintenance task, AL2 is the
distance between the
19
CA 2971897 2017-06-27
location of said current aircraft maintenance task and the location of the
aircraft maintenance
task assigned for the candidates following said current aircraft maintenance
task. In the case that
there is no prior aircraft maintenance task or the task location thereof is
unavailable, replace the
ALINs in T>Ts+ ( ALI+AL2 ) /Vs with AT. In the case that there is no following
aircraft
maintenance task or the task location thereof is unknown, replace the AL2Ns in
T>Ts+ ( ALI+AL2 ) /Vs with AT. For example, suppose ALI, after calculation, is
0.1 km and
AL2 is 0.2 km, and the obtained Vs is 4.3km/h, it can be calculated that Ts+ (
ALI+Al2 ) /Vs is
0.47 hour based on the data in the example above, less than T (0.67 hour),
that is,
T>Ts+ ( ALI+AL2 ) /Vs is true.
[100] If T>Ts+ ( ALI+AL2 ) /Vs is true in step S206, step S207 follows,
determining whether
the candidates meet the requirements for the location and timing of the
current aircraft
maintenance task. If not, step S208 follows, determining whether the
candidates do not meet the
requirements for the location and timing of the current aircraft maintenance
task.
[101] In the embodiments shown in Figure 3 and the above, the process for
determining
whether the selected candidates meet the requirements for location and timing
comprises two
steps S204 and S206. A person skilled in the art, however, will understand the
process can skip
steps S206 and S207 in another embodiment, and the process can skip steps S204
and S205 in
another embodiment.
[102] The step S206 enables a better determination about whether the
candidates meet the
requirements for location and timing of the current aircraft maintenance task,
improving the time
utilization for maintenance persons.
[103] Back to Fig. 2, if the result in step S105 is yes, step S106 follows.
The candidates are put
into the second collection of candidates and step S107 is performed. If the
result is NO, step
S107 follows.
[104] Step S107, determining if there are candidates not undergoing step S205
in the first
collection of candidates. Put differently, whether there are candidates not
undergoing the
determination step about whether they meet the requirements for location and
timing of the
CA 2971897 2017-06-27
current aircraft maintenance task.
[1051 If the answer in step S107 is yes, back to step S104 to proceed with the
step of
determination if other candidates meet the requirements for location and
timing until all the
candidates in the first collection of candidates are identified. Then, step
S108 follows.
[106] Step 108, selecting the first maintenance person from the second
collection of candidates
to perform the current aircraft maintenance task. In this process, rank the
candidates in the
second collection of candidates in order of time priority based on the
comparison between the
time quantities TA and Ts of each candidate's idling time period to be used
for the current aircraft
maintenance task, wherein a smaller difference between TA and Ts means a
higher time priority,
and rank the distance priority of the candidates in the second collection of
candidates based on
the combined distances of the location of current aircraft maintenance task,
the location of the
aircraft maintenance task prior to the current aircraft maintenance task, and
the location of the
aircraft maintenance task following the current, wherein a shorter combined
distance means a
higher priority. In addition, for each candidate in said second collection of
candidates, calculate
the weighted sum of the time priority and the distance priority using
predetermined weights as a
comprehensive priority of the candidate. In an embodiment, the predetermined
weight of time
priority is set higher than that of distance priority while calculating the
comprehensive priority.
According to one embodiment, select the candidates with the highest or higher
time priority from
the second collection of candidates as the first maintenance person. According
to another
embodiment, select the candidates with the highest or higher distance priority
from the second
collection of candidates as the first maintenance person. According to another
embodiment,
select the candidates with the highest or higher comprehensive priority from
the second
collection of candidates as the first maintenance person.
[107] Step S109, determining the estimated start time and the estimated end
time of the current
aircraft maintenance task based on the information of the first maintenance
person. Such
information may comprise the basic information, information for task
arrangement, and the
average speed Vs. The information for task arrangement may refer to the
estimated start time, the
estimated end time and the task location related to each aircraft maintenance
task assigned to the
maintenance persons in the predetermined time period (e.g. current day). The
idling time period
of the first maintenance person can be calculated by the obtained task
arrangement information.
21
CA 2971897 2017-06-27
According to an embodiment, compare the start time of the idling time period
of the first
maintenance person to be used to perform the current aircraft maintenance task
plus the time
value of ALINs with the start time of the task time period of the current
aircraft maintenance
task, set the later one therebetween as the estimated start time t, of the
current aircraft
maintenance task, and set the value obtained from calculating ti+Ts as the
evaluated end time te
of the current aircraft maintenance task, wherein ALI is the distance between
the location of said
current aircraft maintenance task and the location of the aircraft maintenance
task assigned for
the candidate prior to said current aircraft maintenance task. Then, step S110
follows.
[108] Step S110, determining whether the requirements for maintenance persons
of the current
aircraft maintenance task being met following the selection of the first
maintenance person. For
example, some aircraft maintenance task has predetermined number of persons,
and some
aircraft maintenance task requires a specific qualification (e.g. aircraft
release) for the
maintenance persons.
[109] If the requirements for maintenance persons are met after determination,
step S118
follows. The maintenance task database and the maintenance personnel database
are updated
based on the selected maintenance persons. If the requirements for maintenance
persons are not
met (e.g. the number of the persons) after determination, step S111-S117
follows to proceed with
the selection of maintenance persons until the requirements are met.
[110] Step S111, removing the selected first maintenance person from the
second collection of
candidates.
[111] Step S112, selecting a candidate undetermined in step S113 from the
second collection of
candidates.
[112] Step S113, determining whether the selected candidate meets the
estimated start time and
the estimated end time of the current aircraft maintenance task determined in
step
S109.According to an embodiment, step S113 can be performed by determining
whether the start
time t,' and the end time te' of the idling time period of the candidate to be
used to perform the
current aircraft maintenance task satisfy the determined estimated start time
t, and estimated end
time te. According to an embodiment, whether the start time t,' and the end
time te' of the
corresponding idling time period of the candidate meet said estimated start
time t, and said
22
CA 2971897 2017-06-27
estimated end time te is determined based on, determining whether is greater
than or equal to
the amount of time of AT earlier than t, and te' is greater than or equal to
the amount of time of
AT later than te, and, if they are, the candidate is determined to satisfy
said estimated start time t,
and said estimated end time te. According to another embodiment, whether the
start time t,' and
the end time te' of the corresponding idling time period of the candidate meet
said evaluated start
time ti and said evaluated end time te is determined based on, determining
whether t,' is greater
than or equal to the amount of time of ALI/Vs(if ALI is unavailable or
unknown, replace ALT/Vs
with AT)earlier than t; and te' is greater than or equal to the amount of time
of AL2/Vs(if AL2 is
unavailable or unknown, replace AL2/Vs with AT) later than te, wherein ALI is
the distance
between the location of said current aircraft maintenance task and the
location of the aircraft
maintenance task assigned for the candidate prior to said current aircraft
maintenance task, AL2 is
the distance between the location of said current aircraft maintenance task
and the location of the
aircraft maintenance task assigned for the candidate following said current
aircraft maintenance
task, and Vs is a set speed, and, if the answer is YES, it is determined that
the candidate meet
said evaluated start time ti and said evaluated end time te.
[113] If the answer in step S113 is yes, step S114 follows to put the
candidate to the third
collection of candidates. Otherwise, step S115 follows.
[114] So far, the process of determining the candidate is over. The procedure
goes to step S115,
determining if there are candidates not undergoing the determination step S113
in the second
collection of candidates. Put differently, whether there are candidates in the
second collection of
candidates not undergoing the determination step about whether they meet the
requirements for
estimated start time and estimated end time.
[115] If the answer in step S115 is yes, back to step S112 to proceed with the
step of
determination of other candidates in the second collection of candidates until
all the candidates in
the second collection of candidates are identified. Then, step S116 follows,
determining if the
number of candidates in the third collection of candidates meet the
requirements of the current
aircraft maintenance task. For example, if the current aircraft maintenance
task requires three
maintenance persons, the number of candidates in the third collection of
candidates should be
equal or more than two, otherwise, it shall be determined to fail to meet the
requirements.
[116] If the determination of step S116 is meeting the requirements, step S117
follows,
23
CA 2971897 2017-06-27
selecting other maintenance persons from the third collection of candidates to
perform the
current aircraft maintenance task together with the first maintenance person.
In this process,
likewise, rank the candidates in the third collection of candidates in order
of time priority based
on the comparison result of the time amount TA and Ts of each candidate's
corresponding idling
time period to be used for the current aircraft maintenance task, wherein a
smaller difference
between TA and Ts means a higher time priority, and rank the candidates in the
third collection of
candidates in order of distance priority based on the combined distances of
the location of
current aircraft maintenance task, the location of the aircraft maintenance
task prior to the current
aircraft maintenance task, and the location of the aircraft maintenance task
following the current,
wherein a shorter combined distance means a higher priority. In addition, for
each candidate in
the third collection of candidates, calculating the weighted sum of said time
priority and said
distance priority using predetermined weights as a comprehensive priority of
the candidate. In an
embodiment, set weighting value of time priority greater than that of distance
priority while
calculating the comprehensive priority. According to one embodiment, select
the candidates with
the higher time priority from the third collection of candidates as other
maintenance persons.
According to another embodiment, select the candidates with the higher
distance priority from
the third collection of candidates as other maintenance persons. According to
another
embodiment, select the candidates with the higher comprehensive priority from
the third
collection of candidates as other maintenance persons.
[117] In addition, according to other embodiments, the other maintenance
persons are selected
from the third collection of candidates based on predetermined constraint
conditions including
one or more conditions such as fairness, exception, matching habits, and/or
successful patterns.
Fairness refers to the workload of task, the night shifts and off days
assigned to each
maintenance person at a predetermined period (e.g. one day, one week, one
month and one year)
should be generally the same. Exception means the special case where some
maintenance
persons cannot perform tasks at a particular time period. Regular grouping
stands for the
relationship formed among maintenance persons when perform a task according to
their
collaboration. Requirements for successful practice represent other constraint
conditions
concluded in view of the past task assignments. Such one or more conditions of
fairness,
exception, matching habits, and/or successful patterns are preset or obtained
from big data
24
CA 2971897 2017-06-27
analysis.
[118] If the result of step S116 is determined to fail to meet the
requirements, back to step S108
to reselect the first maintenance person and repeat steps S109 to S116 until
the result of step
S116 is determined to meet the requirements.
[119] If the result of step S116 is determined to meet the requirements, step
S117 follows,
selecting other maintenance persons from the obtained third collection of
candidates to perform
the current aircraft maintenance task together with the first maintenance
person.
[120] Then the procedure goes to S118. The maintenance task database and the
maintenance
personnel database are updated based on the selected maintenance persons. For
example, update
the evaluated start time and evaluated end time of the current aircraft
maintenance task and the
list of selected maintenance persons in the task database, and update task
arrangement
information for maintenance persons in the maintenance personnel database. In
one embodiment,
the updating is conducted on a real-time basis. Alternatively, it can be
updated periodically,
occasionally or as needed.
[121] In the embodiment shown in Fig. 2 and the descriptions above, steps S101-
S118 are
described to have a specific sequence, but it is understood that such steps
are not fixed, and can
be performed in a reversed order or be performed concurrently.
[122] Some aircraft maintenance task requires a specific qualification (e.g.
aircraft release) of
the assigned maintenance persons. In this case, following the selection of
maintenance persons
(e.g. the first maintenance person and other maintenance persons) for the
aircraft maintenance
task, there is a need to identify whether the selected maintenance persons for
said current aircraft
maintenance task include the maintenance persons qualified to release
aircraft. If the
determination result shows that there is no maintenance persons qualified to
release aircraft,
obtain the information of maintenance persons on duty qualified to release
aircraft from the
maintenance personnel database and classify such maintenance persons as the
candidates for
aircraft releasing; and select the maintenance persons qualified to release
aircraft meeting the
requirements for said location and time of said current aircraft maintenance
task from said
candidates for aircraft releasing to perform said current aircraft maintenance
task. Aircraft
releasing task differs from routine work involved in the airport. Generally,
releasing an aircraft
CA 2971897 2017-06-27
only takes a few minutes, which does not require the presence of the aircraft-
releasing person
during the entire task, but the presence before the evaluated end time of the
aircraft maintenance
task. For this reason, the time to release aircraft can be evaluated as a
fixed amount of time TL.
The aircraft-releasing person only needs to arrive at the task location before
the sum of estimated
end time te and TL. Therefore, this requirement and the practical task
arrangements of candidates
for aircraft releasing will lead to appropriate aircraft-releasing person for
the aircraft
maintenance task.
[123] The above describes a sample process to select maintenance persons for
an aircraft
maintenance task. In operation, the management staff may continue to manually
select other
aircraft maintenance tasks as the current aircraft maintenance task and select
the maintenance
persons for the task until all the aircraft maintenance tasks are assigned
with maintenance
persons. Alternatively, the computing device may automatically select each
aircraft maintenance
task and corresponding maintenance persons until all the aircraft maintenance
tasks are assigned
with maintenance persons.
[124] According to the modification shown in the embodiment of Fig.2, the
method to maintain
aircraft in the present invention further includes: in the case that the
aircraft maintenance task
having been assigned to maintenance persons occurs a change that affects the
performance of
other aircraft maintenance tasks, receiving a change request of aircraft
maintenance task and
reassigning the affected aircraft maintenance task (including the aircraft
maintenance task
experiencing the change and other affected aircraft maintenance tasks) to
maintenance persons
based on the method above. According to one embodiment, the change request of
said aircraft
maintenance task comprises one or more following changes: addition or
subtraction of aircraft
maintenance task, maintenance level of aircraft maintenance task, location of
aircraft
maintenance task, timing of aircraft maintenance task, and maintenance
persons.
[125] According to an embodiment of the present invention, a computing device
(including a
remote server) for performing the method for maintaining an aircraft is
communicably connected
to a data system of aircraft. Figure 5 shows a computing device communicably
connected to a
data system 600 of aircraft according to an embodiment of the present
application.
[126] One feature of such systems is to obtain the data through real-time
monitoring. A
message containing specific data will be generated automatically when some
triggering
26
CA 2971897 2017-06-27
conditions are met. For example, the method for maintaining an aircraft
according to the
embodiments of the present application comprises receiving fault message sent
by aircraft data
system to automatically generate an aircraft maintenance task, and allows an
automatic selection
of maintenance persons for the generated aircraft maintenance task.
[127] Take ACMS system for example, it has the two important functions as
follows:
[128] Collecting, processing and recording the parameters of an aircraft. Such
parameters are
stored in an internal memory or an external recorder of a data collecting
unit, such as Digital
AIDS Recorder (DAR) Quick Access Recorder (QAR).
[129] Generating system message. Message will be generated when some aircraft
states or
system parameters meet the conditions to trigger message. Such messages are
stored in the loss-
proof memory of the data collecting unit.
[130] When an aircraft is in an abnormal state, e.g. an alarm occurs as a
result of abnormal
parameter, ACMS system will record such an abnormal situation and generate
corresponding
fault message on the basis of the situation and send it to the ground station
of airlines.
[131] In addition to the ACMS system, the CMC system on the aircraft will send
fault
information and cockpit warning information generated by the self-examination
systems to the
ground through message.
[132] One embodiment of fault message transmission is Aircraft Communication
Addressing
and Reporting System (ACARS). ACARS is a digital data link system that
transmits message
(short message) through wireless or satellite between aircraft and a ground
station and provides
service for air-ground and ground-ground mass traffic data communication of
airlines, to realize
the exchange of various information.
[133] ACARS system sends and receives very-high-frequency wireless digital
message from
ground. On the ground, it possesses a network provided by a ground station 410
of a wireless
transceiver that can receive or send message (data link message). The ground
stations, typically
owned by individual service providers generally, send the received messages to
the servers of
different airlines on the network.
[134] On one hand, ACARS enables a flying plane to provide such real-time
information as
27
CA 2971897 2017-06-27
flight dynamics and engine parameters automatically and other information to
the ground station
of airlines, without intervention of the crew members. On this basis, the
operation control center
of airlines allow them to have full access to the flight states of their
aircrafts through a great deal
of real-time and continuous flight data and other information obtained from
their own operating
systems, making possible a real-time monitoring on the aircrafts and meeting
the requirements
for navigation, operation, maintenance and management of other sectors. On the
other hand, the
ground station can provide a variety of services for the aircrafts in flight,
including
meteorological information, route condition, and troubleshooting for emergency
fault in air, thus
upgrading the flight safety and service for passengers. As VHF ground-air
communication
channel is saturated with less information transmitted in low speed, the two-
way data
communication system can make a difference in communication support between
ground and air.
[135] Based on the computing device (including a remote server) to perform the
method for
maintaining an aircraft in the embodiments of the present application, the
ground station of
airlines can receive the fault message. The computing device analyzes the
fault message by
loading its information and then adds one or more aircraft maintenance tasks
to the maintenance
task database.
[136] According to an embodiment of present invention, after the selection of
aircraft
